SLIDING-POLE-OPENING GUARD.

Specification of Letters Patent.

Application filed June 22, 1910. Serial No. 568,333.

as is used in fire-engine houses, and has for one of its objects theprovision of a device that is capable of being secured to the wall orother upright support at one side of the opening and consisting of twoarms so constructed and mounted that when they are in position to guardthe opening they form a continuous rail, but when they are moved toexpose the opening separate so that the pole does not interfere withtheir movement.

Another object of my invention is the provision of a device that isactuated by springs into an inoperative position, being held in 'itsguarding position by a slidable catch that is released by mechanismconnected with the fire-alarm system.

My invention will be described in detail hereinafter, and illustrated inthe accompanying drawings, in which- Figure l is a view of the interiorof the firemens dormitory, showing the slidingpole and opening with myimproved guard in operative position; Fig. 2, a front view in aninoperative position; Fig. 3, a similar view in a guarding position;Figs. 4, 5, 6, and 7, detail views of the hooks on the guard-arms; andFig. 8, a side view of the latch-bar.

In the drawings similar reference characters will indicate correspondingparts throughout all of the views.

My improved guard may, as shown, be secured to the wall A of thefiremens dormitory adjacent to the sliding-pole opening B and at asufficient height above the floor to form an effective barrier toprevent any one from stepping into the opening accidentally, Cdesignating the sliding-pole.

My guard consists of a base-board 1 secured to wall A and havinjournal-boxes 2 and 3 secured thereto, saitf boxes being arranged sothat the journal-boxes 2 near the middle of the base are on a higherplane than the journal-boxes 3, adjacent to the ends of the base.

4 indicates the two guard-arms, each consisting of a rod or length oftubing having an outwardly-extending portion 5, with its outer end benttoward the other arm, as shown at 6, while its other end is bent atright angles to the portion 5, slightly upwardly, as shown at 7, andjournaled in boxes 2 and 3. By this construction it will be apparentthat when the arms are in their lowered position to guard the opening Btheir ends are together, as shown, but when they are swung upwardly toexpose the openings the ends of the arms are thrown away from oneanother, so that they will pass the pole C without interfering with oneanother.

8 indicates coil-springs mounted on the ends 7 of the arms 4 and havingone of their ends secured to journal-boxes 2 and their other endssecured to collars 9, secured to the arms by means of set-screws 9.

10 indicates a latch-bar slidably mounted on base 1 and held normally ina raised position by lneans of spring 11, and 12 a roller journaledlaterally on one side of the bar.

13 indicates a hook secured to the end 7 of one bar 4 and provided witha socket 14 to receive a lug 15 on hook 16, secured to the other bar,while 17 indicates a beveled lug on the side of hook 13 to engage roller12. From this construction it will be understood that the arms 1 areheld normally in their raised or inoperative position by means ofsprings 8, and when moved manually downward the beveled lug 17 engagesthe roller 12 and moves the latch-bar 10 downwardly against theresistance of spring 11. When the arms 4 reach their lowermost position,the lug 17 passes from engagement with roller 12 and the spring 11raises the bar so that the roller comes to rest under the lug 17 and thearms are held in their lowered position against the resistance of spring8.

18 indicates a casing secured above the latch-bar 10 and having aweighted arm 19 mounted therein, said casing being connected to thefire-alarm system by means of wires 20 and having mechanism therein thatholds the arm 19 normally raised, butwhen the alarm is sounded the armis released and striking latch-bar 10 slides it downwardly, so that theroller 12 is moved from engagement with lug 17 and the arms 4 are swungupwardly by the action of springs 8.

21 indicates an arm secured to the portion 7 of one of the arms 4:, and22 a rope secured thereto and extending down into the engineroom topermit moving the guard-arms to Patented Jan. 24, 1911.

their operative position from the engineroom,

23 indicates spring-arms secured to base 1 that act as buffers tocushion the arms when they reach their uppermost positions.

24 indicates antifriction rollers for the latch.

Having thus described my invention, what I claim is 1. A guard devicefor openings in floors and similar places comprising a baseboard, journal-boxes secured thereto, arms journaled in said boxes, and springsnormally i tending to raise the arms, substantially as 1 the journaledends of said arms, and a latchbar slidably mounted on said base toengage the hooks and hold the arms extended against the resistance ofthe springs, substantially as shown and described.

4. A guard device for openings in floors and similar places comprising abase-board, journal-boxes secured thereto, arms jour naled in saidboxes, springs normally tending to raise said arms, a hook on one arm 11and having a socket therein, another hook secured to the other arm andengaging the socket in the first mentioned hook, and a latch-barslidably mounted on said base to engage the first-mentioned hook whenthe 1 arms are in extended positions to hold them against the resistanceof the springs, substantially as shown and described.

5. A guard device for openings in floors and similar places comprising abase-board, journal-boxes secured thereto, arms journaled on said boxes,coil-springs mounted on the journaled ends of the arms, one end of eachspring secured to one of the journalboxes, the other end of each springsecured to the arm and normally tending to raise the arm, hooks securedto the ends of the arms, one of said hooks having a socket and the otherhook engaging the socket, the firstmentioned hook having a beveled lugthereon, and a latch-bar adapted to engage the lug aforesaid to hold thearms extended, substantially as shown and described.

6. A guard device for openings in floors and similar places comprising abase-board, journal-boxes secured thereto, arms journaled on said boxes,coil-springs mounted on the journaled ends of the arms, one end of eachspring secured to one of the journalboxes, the other end of each springsecured to the arm and normally tending to raise the arm, hooks securedto the ends of the arms, one of said hooks having a socket and the otherhook engaging the socket, the firstmentioned hook having a beveled lugthereon, a latch-bar having a roller journaled laterally thereof andadapted to engage the beveled lug, a spring engaging said latchbar tohold it in a raised position, and the roller in engagement with the lugaforesaid, and a weighted arm suitably supported and adapted to bereleased and strike the latch-bar to move it downwardly and release theroller from engaging the lug, substantially as shown and described.

In witness whereof, I have hereunto set my hand in presence of twosubscribing witnesses.

EDWARD C. DELENE.
